COOLING FAN INSTALLATION
WARNING: To ensure that drive is not unexpectedly started,
turn off and lock out or tag power source before proceeding.
Remove all external loads from drive before removing or
servicing drive or accessories. Failure to observe these
precautions could result in bodily injury.
Unpack all components and inspect for shipping damage. Do
not use any component that has been damaged or modified.
Make sure all components are clean and free of any foreign
material prior to assembly. Cooling fan assembly is designed to
fit onto the input shaft before placement of sheeves or belt
guard assembly.
Installation for TA4207CF and TA5215CF:
1. Referring to Figure 2, install tapered bushing (9) into bore of
fan blade assembly (2) and loosely install the three set screws
provided with fan. Snug set screws but do not tighten at this
time.
2. Slide fan assembly onto input shaft and install input shaft
key. Note: Key is supplied with the TAII reducer. Locate fan
blade edge distance “A” (Figure 1) from end of shaft per Table
1. Make sure fan assembly rotates without interference when
input shaft is rotated.
3. Alternately tighten the set screws until fan assembly is
securely installed on the input shaft.
4. Recheck fan assembly for proper location and clearance.
Loosen set screws and repeat steps 2 and 3 above if not
properly located.
Installation for TA6307CF through TA12608CF:
1. Referring to Figure 2, install fan guard back plate assembly
(1) using the four bolts (4) provided. Note that the screen is
mounted towards the reducer. Tighten to recommended torque
in Table 1.
CAUTION: Fan guard screen has sharp edges. Use caution
when installing to avoid lacerations.
2. Slide fan blade assembly (2) onto input shaft and install key
and set screws (5). Note: Key is supplied with the TAII reducer.
Position fan blade edge distance “A” (Figure 1) from end of shaft
per Table 1. Make sure fan assembly rotates without
interference when input shaft is rotated. Tighten the two fan
blade set screws (5) securely.
3. Install fan guard cover (3) with four bolts (6), lockwashers (7),
and hex nuts (8). Tighten securely.
4. Verify fan blade rotates freely and does not interfere with fan
guard back plate (1) or fan guard cover (3). Adjust fan blade if
necessary.
